Aortic stiffness was significantly associated with albuminuria in individuals with type 2 diabetes (OR 2.55; 95% CI 1.30-4.98), but not in those without diabetes (OR 0.96; 95% CI 0.63-1.45).

Aortic stiffness and stroke are associated with albuminuria in individuals with type 2 diabetes but not in those without diabetes, suggesting distinct pathophysiological links between macro- and microvascular dysfunction depending on diabetes status.
Effect estimate: OR 2.55 (95% CI 1.30-4.98)
BACKGROUND: Although the associations between measures of macrovascular and microvascular dysfunctions are well characterized in diabetes, there is limited data on these associations in individuals without diabetes. We compared the associations between macrovascular dysfunction and renal microvascular dysfunction in individuals with type 2 diabetes (T2D) and without diabetes. METHODS: Cross-sectional analyses of baseline data from the multiethnic Healthy Life in an Urban Setting (HELIUS) study (Amsterdam, the Netherlands), including 986 participants with T2D and 7680 participants without diabetes were done. Logistic regression analyses were used to examine the associations between macrovascular dysfunction aortic stiffness, coronary artery disease (CAD), peripheral artery disease (PAD), and stroke and renal microvascular dysfunction albuminuria with adjustments for age, sex, ethnicity, waist-to-hip ratio, systolic blood pressure, LDL-cholesterol, and smoking (and HbA1c and diabetes duration for the T2D group). RESULTS: In the fully adjusted models, aortic stiffness was associated with albuminuria in individuals with T2D OR 2.55; 95% CI,1.30-4.98, but not without diabetes 0.96; 0.63-1.45; stroke was associated with albuminuria in T2D 2.40;1.10-5.25, but not in non-diabetes 1.39;0.83-2.33. In age-sex adjusted models, CAD was associated with albuminuria in T2D 1.65;1.09-2.50 and in non-diabetes 1.56;1.13-2.15; the associations were no longer significant in the fully adjusted model. There were no associations between PAD and albuminuria in T2D and non-diabetes. CONCLUSIONS: Our study shows important differences in the associations between measures of macrovascular and renal microvascular dysfunction in T2D and non-diabetes. These findings provide opportunities for future research aimed at prevention and treatment strategies for individuals with vascular dysfunction.
Hayfron‐Benjamin et al. (Tue,) conducted a cross-sectional in Type 2 diabetes (n=8,666). Macrovascular dysfunction (aortic stiffness, stroke, CAD, PAD) vs. Individuals without diabetes was evaluated on Renal microvascular dysfunction (albuminuria) (OR 2.55, 95% CI 1.30-4.98). Aortic stiffness was significantly associated with albuminuria in individuals with type 2 diabetes (OR 2.55; 95% CI 1.30-4.98), but not in those without diabetes (OR 0.96; 95% CI 0.63-1.45).
